NullReferenceException at SalvageItemFixed

even though i gave myself perms, whenever i try /rec i get that message, i gave the default group perms and that worked for that group not sure what's going on by adding a player to the perms. adding a group works fine i think.
recycle.use to groups and/or players is working correctly. (19:54:50) | Failed to call hook 'OnItemAddedToContainer' on plugin 'Recycle v2.1.6' (NullReferenceException: Object reference not set to an instance of an object)

I tested the recycling of every single item in the game and could not reproduce your error.
